Currently if an admin wants to update the hosts connected to Cloudstack. CloudStack, he needs to search the released updates from a given source URL and check the updates as per the applicable XenServer version. Then admin needs to compare them with the already applied patches to find out the available updates. To reduce this effort we are adding this feature to CloudstackCloudStack.

This feature will list the available patches/hotfixes for hypervisors connected to Cloudstack and the Cloudstack managed by CloudStack. CloudStack admin will be able to see the available updates on Cloudstack UI, this . This is a functional specification of feature "XS alert hotfix updates notification" which has Jira ID _CLOUDSTACK-192

...

• Requirements
  • Surface up the list of all released updates applicable to XenServers hosts managed by CloudStack and display them by means of APIs or on CloudStack UI dashboard so that admin can have the list of available updates and take appropriate action to install them manually.
• Non-requirements
  • Cloudstack will only list the available updates and it is not responsible for applying the updates on the host.
  Test guidelines
  • Functional test
• Configuration
  • There are two global configuration parameters:
    • xen.update.url - URL to get latest Xenserver Updates. Default value for it is http://updates.xensource.com/XenServer/updates.xml;
    • update.check.interval (in sec) - How frequently should CloudStack check for Xenserver Updates. By default CloudStack will check for new updates once a week.
• User permission
  • Root-Admin would have privilege to list the available updates.
